CAS Number: 127869-51-6 Molecular Weight: 2198.1 Salt Form: Acetate Purity: >96% Sequence (3-letter): Gly-Leu-Ser-Lys-Gly-Cys-Phe-Gly-Leu-Lys-Leu-Asp-Arg-Ile-Gly-Ser-Met-Ser-Gly-Leu-Gly-Cys-OH [Cys6-Cys22] Sequence (1-letter): GLSKGCFGLKLDRIGSMSGLGC-OH Storage: -20 ?C or below CNP(1-22) is a biologically active, peptide fragment of C-Type Natriuretic Peptide, a cardiovascular hormone involved in the maintenance of electrolyte-fluid balance and vascular tone. CNP is a selective endothelium-independent venodilator and is a selective ligand for the NPR-B (NPR2) receptor. CNP is produced in most endocrine glands. CNP-22 is the same sequence in human, mouse, bovine, pig and other mammals
